The Server Administrator Remote Access Service provides a complete remote system management solution for SNMP- and CIM-instrumented systems equipped with a Dell Remote Access Card (DRAC) III, a DRAC III/XT, an Embedded Remote Access (ERA) controller, an ERA Option (ERA/O) card, or an ERA/MC controller. These hardware and software solutions are collectively known as remote access controllers (RACs).
The Remote Access Service provides remote access to an inoperable system, allowing you to get the system up and running as quickly as possible. The Remote Access Service also provides alert notification when a system is down and allows you to remotely restart a system. Additionally, the Remote Access Service logs the probable cause of system crashes and saves the most recent crash screen.
You can log into the Remote Access Service through the Server Administrator home page or by directly accessing the controller's IP address using a supported browser.
See the Server Administrator Command Line Interface User's Guide and the Dell Remote Access Controller Racadm User's Guide for information about running the Remote Access Service from the command line.
When using the Remote Access Service, you can click Help on the global navigation bar for more detailed information about the specific window you are viewing. Remote Access Service help is available for all windows accessible to the user based on user privilege level and the specific hardware and software groups that Server Administrator discovers on the managed system.
NOTE: The Remote Access Service is not available on modular systems. You must directly connect to
the remote access controller (RAC) on a modular system. See the Dell Embedded Remote Access/MC
Controller User's Guide for more information.
NOTE: See the Dell Remote Access Controller Installation and Setup Guide for complete information
about installing and configuring a DRAC III, a DRAC III/XT, or an ERA/O controller, configuring an ERA
controller, and using a RAC to remotely access an inoperable system. See the Dell Embedded Remote
Access/MC Controller User's Guide for complete information about configuring and using an ERA/MC
controller to remotely manage and monitor your modular system and its shared resources through a
network.

Configuring the RAC Network Properties
NOTE: You must have Admin privileges in Server Administrator to use the Remote Access Service.
Your RAC contains an integrated 10BASE-T/100BASE-T Ethernet NIC and supports TCP/IP. The NIC has a default address of 192.168.20.1 and a default gateway of 192.168.20.1.
NOTE: If your RAC is configured to the same IP address as another NIC on the same network, an IP
address conflict occurs. The RAC stops responding to network commands until the IP address is
changed on the RAC. The RAC must be reset even if the IP address conflict is resolved by changing the IP
address of the other NIC.
NOTE: Changing the IP address of the RAC causes the RAC to reset. If SNMP polls the RAC before it
initializes, a temperature warning is logged because the correct temperature is not transmitted until the
RAC is initialized.
To configure the network properties of your RAC, perform the following steps:
Click the Main System Chassis object on the Server Administrator home page, and then click
the Remote Access Controller object.
Click the Configuration tab.
The Configure Network Properties window appears.

Configuring DRAC III Dial-in (PPP) Users and Modem Settings
Dial-in (PPP) users and modem features are currently only available for the DRAC III.
Adding and Configuring a DRAC III Dial-In (PPP) User
NOTE: You must have Admin privileges in Server Administrator to use the Remote Access Service.
This subsection describes how to add and configure a dial-in (PPP) user. After dial-in users are authenticated, they must enter the RAC user authentication at the remote access controller login screen to access the DRAC III.
NOTE: The Server Administrator managed-system PPP client uses the 192.168.234.235 network to talk
with the installed DRAC III. It is possible that this network IP address could already be in use by other
systems or applications. If this situation occurs, the PPP connection fails to operate. If this address is
already in use, the user is required to change the managed-system PPP client IP address to a different
number. To change the managed-system PPP server IP address to use another network so that conflicts
do not occur, you must use the racadm utility. See the Dell Remote Access Controller Racadm User's
Guide for information about using the racadm utility.
To add and configure dial-in users, perform the following steps:
On the Server Administrator home page, click the Main System Chassis object, and then
click the Remote Access Controller object.
Click the Configuration tab.
Click Dial-In Users.

This number is the one the Remote Access Service calls if Callback Type is set to Preset.
Select a setting from the Callback Type drop-down menu:
None When called, the Remote Access Service does not disconnect and call back; the connection remains active.
Preset When called, the Remote Access Service disconnects and calls the number specified in the Callback Number field; this setting activates the callback number control.
User Specified When called, the Remote Access Service asks the user for the callback number. Then the Remote Access Service disconnects and calls the number the user specified.
Click Apply Changes and then click OK to save your changes.
Adding and Configuring DRAC III Demand Dial-Out Entries
NOTE: You must have Admin privileges in Server Administrator to use the Remote Access Service.
If you set the dial-in (PPP) setting to Preset, the demand dial-out entry causes the Remote Access Service to disconnect and call the management station back at a preset number. Upon callback, you must provide your RAC user authentication to access the Remote Access Service.
NOTE: The RAC managed system software uses a PPP connection to talk to the installed RAC. The IP
address for this PPP connection is 192.168.234.235. It is possible that this network IP address could
already be in use by other systems or applications. If this situation occurs, the PPP connection fails to
operate. If this address is already in use, the user is required to change the managed-system PPP client
IP address to a different number. To change the managed-system PPP server IP address to use another
network so that conflicts do not occur, you must use the racadm utility. See the Dell Remote Access
Controller Racadm User's Guide for information about using the racadm utility.
To add a demand dial-out entry, perform the following steps:
On the Server Administrator home page, click the Main System Chassis object, and then
click the Remote Access Controller object.

Configuring the RAC Remote Features Properties
NOTE: You must have Admin privileges in Server Administrator to use the Remote Access Service.
If the local boot image on the managed system has been corrupted, a RAC has the ability to boot its host server using a diskette boot image that it downloads from a Trivial File Transfer Protocol (TFTP) server. This feature is called remote floppy boot. A RAC can also update its firmware using a firmware image located on a TFTP server. This feature is called remote firmware update, and the process is similar to flashing a system BIOS.
To configure the remote floppy boot feature and the remote firmware update feature of your RAC, perform the following steps:
Click the Main System Chassis object on the Server Administrator home page, and then click
the Remote Access Controller object.
Click the Configuration tab.
The Configure Network Properties window appears.

Configuring RAC Security
NOTE: You must have Admin privileges in Server Administrator to use the Remote Access Service.
NOTE: See the Dell Remote Access Controller Installation and Setup Guide for more information about
RAC security features.
To configure your RAC security from the Server Administrator home page, click System→ Main System Chassis→ Remote AccessController and then click the Security tab. Under the Security tab, you can perform CSR certificate management and set RAC user login authentication options.
Certificate Management
Use the Certificate Management window to generate a certificate signing request (CSR), upload a server certificate or certificate authority (CA) certificate to the RAC firmware, or view an existing server certificate or CA certificate. From the Certificate Management window, the following options are available:
A CSR is a digital request to a CA for a secure server certificate. Secure server certificates ensure the identity of a remote system and ensure that information exchanged with the remote system cannot be viewed or changed by others. To ensure the security for your RAC, it is strongly recommended that you generate a CSR, submit the CSR to a CA, and upload the certificate returned from the CA.
A certificate authority is a business entity that is recognized in the IT industry for meeting high standards of reliable screening, identification, and other important security criteria. Examples of CAs include Thwate and VeriSign. Once the CA receives your CSR, they review and verify the information the CSR contains. If the applicant meets the CA's security standards, the CA issues a certificate to the applicant that uniquely identifies that applicant for transactions over networks and on the internet.
After the CA approves the CSR and sends you a certificate, you must upload the certificate to the RAC firmware. The CSR information stored on the RAC firmware must match the information contained in the certificate.
Generating a CSR
NOTICE: Each new CSR overwrites any pervious CSR on the firmware. It is crucial that the CSR on the
firmware matches the certificate returned from a CA.
From the Certificate Management window, select the Generate a new CSR option and click
Next.
The Certificate Signing Request (CSR) Generation window appears.
Type a value or choose a value from a drop-down menu for each listed attribute and click
Generate.
A message appears stating that the CSR was successfully generated and giving the path where it was saved.
You are now ready to send your CSR to a CA.
Uploading a Certificate
To upload your server certificate or CA certificate to the RAC firmware, the certificate must reside on the RAC's host server. You must designate the CSR type, the exact filename, and the absolute file path to the certificate on the server. Then, click Upload.
NOTE: Failure to enter the correct path for the location of the certificate on the host server does not
result in a warning message.
From the Certificate Management window, select the Upload certificate option and click
Next.
The Upload Certificate window appears.
Select the certificate type from the drop-down menu.
The selections are Server Certificate and CA Certificate.
Type the exact path and filename of the certificate to be uploaded.
NOTE: When you have a fully qualified path or filename that contains spaces, you must place
double quotation marks around the string. For example, if your file is contained in c:\security
files\certificates\sslcert.cer, you must place the fully qualified path name and filename in double
quotations because a space appears between "security" and "files." For example: "c:\security
files\certificates\sslcert.cer".
Click Upload.
A message appears stating that the certificate was successfully uploaded to the RAC firmware.
Reset the RAC to enable the new certificate.
NOTE: You must reset the RAC after uploading the certificate to ensure that the new certificate is used.
